was out in the yard and wanted to take a pano of a big willow tree but i didnt want to break out the nodalninja so i just took my 20D and 35mm f1.4 and shot at f/18 from about 5 feet away from the tree. i was positioned at ground level. suprisingly i can not find one stitch error, but i do see one blending error (not to bad but it is there in the trunk of the tree)
